Dynamic Relative magnetic permeability

  1. Oct 29, 2015 #1
    I want to know that are there any materials or methods by which their relative magnetic permeability (μr) be instantaneously,continuously & periodically varied. Kindly provide the reference document/video for the description if possible.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    Depending on your application, you could use a traditional Magnetic Amplifier, or something similar:

    The concept is to vary the level of saturation of the magnetic material, which effectively modulates the value of μr.

    thank you very much,Sir! I hope to use the magnetic amplifier concept. Do you know where can I get its technical information? like from it's working principle to it's graphs of μr vs time & μr vs current?

    I would probably start with the wikipedia page, and follow some of the additional links to other resources... :smile:
